Column 1 lists country codes. Most
correspond to the Singer-Small list, except in the cases of successor states and
newly unified states, where I invent a few codes in order to distinguish the
cases. (For example, the ELF for Russia is different from the Soviet Union and so
these cases do not have the same code.)

Column 2 lists country names.

Columns 3 to 5 reprint the indices published in
Charles Lewis Taylor and Michael C. Hudson. 1972. World Handbook
of Political and Social Indicators, 2d ed. New Haven: Yale University
Press. Pp. 271-274.

In my own data for 1961 and 1985 I
calculate the ELF in three different ways. Each index uses the Taylor and
Hudson formula, but the three indices differ from one another in what they
consider an ethnic group. You must make a decision that will
be determined in large part by your research question and your own definitions of ethnicity:

Columns 6 and 9 report an ELF Index
(for 1961 and 1985, respectively) that uses none of the groupings reported in the sources when data on sub-groups
are available. (For example, it treats separate Native American groups as separate ethnic groups rather than
combining these
in a catch-all "Indigenous Peoples". Similarly, it
treats Hutus and
Tutsis as separate ethnic groups rather than grouping these as Banyarwanda in
Rwanda or Barundi in Burundi). In addition, in settler societies of the
Western Hemisphere, this index treats racial distinctions within
ethnolinguistic groups (Afro-Americans versus White Americans or Afro-Colombians
versus Euro-Colombians) as separate ethnic groups.

Columns 7 and 10 report the ELF
Index (for 1961 and 1985, respectively) if racial distinctions within linguistic
groups do not constitute separate ethnic groups. (In this index, for example,
White and Black Americans constitute a single ethnic group. Similarly, Afro-Colombians, Euro-Colombians, Mestizo-Colombians,
and Mullato-Colombians are simply Colombians.)
Note that Taylor and Hudson are inconsistent in this; they make this distinction in
the United States but not in other Western Hemisphere societies. Note: Columns 7
and 10 show only the ELF Indices that differ from Columns 6 and 9, respectively.
(That is, to use this column you must fill in the blank spaces from the previous
column.)

Columns 8 and 11 report an ELF Index
(for 1961 and 1985, respectively) that groups racial and cultural sub-groups
within linguistic groups in ethnic groups defined by language. (In this index,
for example, all Arabs in Kuwait constitute a
single ethnic group rather than separate Kuwaiti, Syrian, Palestinian, and other
ethnic groups. The groupings are indicated in column 12. Note: Columns 7 and 10
show only the ELF Indices that differ from the previous columns. (That is, to
use this column you must fill in the blank spaces from the previous columns.)

Column 12 (Annotations) lists the
groups that affect the calculation of the ELF Index in columns 8 and 11. A
name without parentheses (for example, Arab) indicates the group that is made up
of
sub-groups. A list of names linked by pluses and placed in parentheses
indicates the constituents of a group.
